General Motors has streamlined the electric vehicle ownership experience with the launch of Energy Pass, a unified interface within its myChevrolet, myCadillac, and myGMC applications. Announced in San Francisco, this feature grants users access to nearly 70% of U.S. fast-charging stations, including networks operated by Tesla, Electrify America, and GM’s joint venture, Ionna.
The platform enables drivers to locate stations, initiate sessions, monitor live status, and consolidate receipts without switching apps. Exclusive discounts are also available at select networks. To further standardize compatibility, all 2027 GM EVs will feature North American Charging Standard (NACS) inlets natively, eliminating the need for adapters required by older Combined Charging System (CCS) models. An over-the-air update later this year will introduce Plug & Charge capabilities on the Tesla Supercharger network, automating payment upon connection.
Beyond consumer convenience, GM is positioning its fleet as a critical component of national energy infrastructure. The company is rolling out firmware updates that enable full vehicle-to-grid (V2G) capabilities for its Energy home systems. This bidirectional charging allows utilities to purchase excess energy from parked EVs during peak demand, potentially lowering consumer electricity bills. Currently, 250,000 GM EVs possess V2G hardware, with active pilot programs underway in Michigan and California.
In a strategic move to diversify supply chains, GM is accelerating research into sodium-ion battery technology. Partnering with Peak Energy and financed by GM Ventures, the automaker aims to develop grid-scale storage cells using sodium, an abundant and cost-effective alternative to lithium. While sodium-ion batteries offer lower energy density than lithium-ion, making them less ideal for lightweight vehicles, their superior cycle life and material accessibility make them optimal for stationary energy storage. Full performance cells are expected within two years, reinforcing GM’s long-term competitiveness against global rivals.
